About This Product
Iodine shows a solid turning straight into vapour, and is used to teach sublimation and halogen properties. All work takes place in a fume hood or approved ventilated enclosure with gloves and eye protection, and vessels are kept covered where possible to limit vapour release. Iodine is never heated in an open classroom, since the vapour irritates the eyes, skin and airways. The Iodine Research Laboratory Reagent is available for supply within India and for export to Albania, Kiribati, Libya, Mali and Costa Rica.
Frequently Asked Questions
Q1. What happens when iodine crystals are warmed gently?
They sublime, passing directly from solid to a violet vapour. This is done only in a fume hood or ventilated enclosure because the vapour is irritating.
